FLANGlNG-IVIACHINE.

Specification of Letters Patent.

- Patented Nov. 21, 1905.

Application filed January 29, 1903. Renewed March 4, 1904:. Serial No. 196,489.

To (tZZ whom, it may concern:

Be it known that 1, CHARLES W. SLEEPER, a subject of His Majesty the King of Great Britain, and a resident of Lancaster, in the county of Coos and State of New Hampshire, have invented certain new and useful Improvements in Flanging-h/Iachines, of which the following is a specification.

My invention relates to improvements in mechanism for fianging cans, which is the process of turning a portion of the end of a can-body outward or inward at an angle with the axis of the can. i

The machine shown and described is especially designed to turn the flanges outward upon both ends of a so-called square can. It is obvious, however, that by changing the shape of the dies the machine may be used for flanging cans of other shapes upon one or both ends.

Figure 1 is a front elevation of my machine. Fig. 2 is an elevation of the right side. Fig. 3. is an elevation of the left side. Fig. 4 is a top view. Fig. 5 is a detail showing the top of the table and the feed-chain. Fig. 6 is a top View, and Fig. 6 a side View, of the chuck C with its jaws closed. Fig. 7 is a top view, and Fig. 7 a side view, of the chuck C with its jaws open. Fig. 8 is a front View, and Fig. 8 a side view, of the mechanism for raising the bottom die. Fig. 9 is a side View of the gate B. Fig. 10 is a top view of the gate B, showing the same closed. Fig. 11 is atop view of the gate B, showing the same opened. Figs. 12 and 13 are details showing the action of the dies. Fig. 14 is a side elevation of a can-body after the same is flanged. Fig. 15 is a side and a plan view of astripper Fig. 16 is a plan view of the yoke g and strippers 9. Fig. 17 is a group of details showing the crank-pinion c and sliding block 0*. Fig. 18 is a top and a side View of the jaws 0. Fig. 19 is a side view of the cam dand cam-rod cl with the parts connected therewith.

A is the frame of the machine.

A is the table.

A is a driving-shaft provided with a friction clutch-pulley A and means for operating the same.

A is a spur-pinion on the shaft A engaging a gear A upon the crank-shaft A.

A is a connecting-rod adjustably connecting the crank A with the ram A which is suitably guided in the face of the frame A.

chain connects a sprocket-wheel (4 upon the shaft A with a similar wheel a upon a shaft a, which also carries a barrel-cam c engaging suitable rollers a a upon the side of the feed-chain (4 which passes over idle wheels a a and rests upon the feed-tables a a The cam a gives intermittent progressive motion to the chain a with periods of rest equal to about twice the periods of motion. The links of the chain (0 are large enough to allow the can-body to drop loosely into them and rest upon the tables a (0 Between the tables a" and a is a gate B, Figs. 9, 10, 11, composed of two steel plates 7) and 6, arranged to slide longitudinally one upon the other in opposite directions. The plateb rests upon one end of the plate 6, which is slightly depressed, so that the upper surfaces of the two' plates are. on a level with each other. The plate 6 has a rectangular opening through it somewhat larger than the links of the chain a and has a rack t secured face upward to one end. A rack b is secured face downward to the plate 6. A pinion b upona stud projecting from a hanger 5 engages the racks b 6 in such manner that when one of the'racks is moved the other moves in the opposite direction. Fig. 10 shows the gate B closed, the dotted line 8 showing the position of a can-body resting upon the plates 6 b. Fig. 11 shows the gate B opened to allow the can-bodys to drop through the gate. The gate B is opened andclosed by the lever 6, which engages a pin 6 upon the side of the rack 6 The lever b is pivoted to an arm 6 attached to the frame of the machine, and is provided with a cam-groove b", engaged by a pin and roller 6 secured in an arm 6, projecting from the face of the ram A Directly below the gate B and in vertical alinement with the center line of the ram A is placed a chuck C, Figs. 6 and'7, which has in its upper face four converging channels in the form of a Greek cross. In each of these channels is a sliding jaw c, carrying on its inner end a die-holder 0 to which-is secured a die 0. The dies 0 are made with their inner faces exactly fitting the outside ofthe canbody to be operated upon and of a height equal to the distance between the flanges of rod 6 screwed into the ram 0 the can and constitute when the flanges of the body are turned outward anvils around which the flange is turned. Each of the jaws 0 has in its under side a transverse rectangular slot 0', in which is a sliding block 0', engaged by a crank c on the upper end of a pinion c journaled in the body of the chuck.

A cam d, secured to the side of the gear A", acts upon a pin and roller (shown in Fig. 19) upon the side of a cam-rod cl, which terminates in a rack which engages a segment-gear (Z upon a rock-shaft (Z journaled in suitable hangers (Z' d, secured to the table A. Segment-gears d d, secured to the rock-shaft (Z engage racks d (P, each of which engages two of the crank-pinions c of the chuck C. The movement of the racks d is equal to one-half the pitch-circumference of the pinions 0 and the pinions are so placed in relation to the racks that at one extremity of their motion the chuck C is closed, as in Fig. 6, and at the other extremity of their motion the chuck C is opened, as in Fig. 7. When the chuck C is closed, the dies 0 exactly fit the outside of the can-body.

Referring to Figs. 2, 4c, and 8, the ram A is provided with projections c e, which when the ram is nearly at the extremity of its downward motion strike and depress a lever e, pivoted in the back of the frame A. The lever a rests upon a post 0 supported by one end of a horizontal lever 6 pivoted upon the end of an adjusting-screw e in the lower part of the frame A. The bottom of the ram 0 rests upon the point of the lever e and is held downward by a compression-spring c' 'upon a The ram slides in a vertical opening in the middle of the chuck C and has secured to its upper face the bottom die f.

The ram A is bored to receive and hold the shank of a die-holder f, to the lower face of Which is secured the top dief The dies ff Figs. 12, 13, are each provided with a flange f the flange and body of the die being made of one piece and the corner between body and flange being rounded so that when the dies approach each other, as in Fig. 12, the rounded corners will bend the edges of the can-body s over the corners of the die 0", and the flanges f will press the said edges against the horizontal faces of the die 0, as shown in Fig. 13, leaving the can 8 flanged, as in Fig. 1 1. The die-holder f and die f are provided with three dovetailed grooves, into each of which is loosely fitted a stripper g, Figs. 8, 15, 16. Thelower ends ofthe strippers are made to fill the grooves through the flangef so as to continue the face of the flange unbroken. The upper ends of the strippers g are provided with transverse notches into which fits a yoke g, which is provided with a hollow shank g, which slides in a suitable projection g in the rear of the ram A A spring g, secured in the hollow shank g and attached to a hook g,

f is withdrawn from the can.

projecting from the ram A serves to hold the yoke g in place. As the ram A rises the yoke g strikes the forked lever e and stops, holding the strippers stationary and preventing the further rise of the can while the die As the ram A descends the spring g holds the yoke and strippers stationary until the strippers are struck by the face of the ram, when all move together through the remainder of the stroke.

In operation the can-bodies are placed on end in the links of the chain at the right side of the machine, Fig. 1, and by continuous motion of the chain are carried forward and placed upon the gate B. As the chain pauses the gate B opens and allows the can-body to fall into the chuck (J, the gate B thus forming a trap in the table. The dies of the chuck C move together toward the can while the top die f enters it and then close lightly upon it. When the top die reaches the position shown in Fig. 12, the bottom die begins to rise and both dies close upon the can, as in Fig. 13. The

chuck C then opens and the ram A. rises with the can held by friction upon the body of dief. When the can has risen sufficiently to clear the gate B, the gate closes and the can is stripped from the die f and falls into the chain and upon the gate B. The chain then moves along, carrying the flanged can-body with it, while it places another body upon the gate ready for flanging.

What I claim, and desire to secure by Letters Patent, is
